IPD Vs Cat Inframe Kit: In-Depth Discussions


IPD’s new piston design is now available as a piston kit, cylinder kit, and chassis overhaul kit. Due to carbon packing, the top land has a reduced diameter that reduces oil consumption as well as minimizing liner polishing.

The highland specification prevents any carbon from forming between pistons and liners, so any carbon that does form will flake off.

IPD has developed a unique and superior one-piece oil dam design to compete with two-piece designs. Pistons made by IPD-steel are constructed in Torrance, California (United States).

Using the latest technology, the Cat cylinder heads are entirely remanufactured.

They have been updated to include substantial design improvements, resulting in the same performance & long life as new. Caterpillar has replaced critical components that wear and seal during operation.

Genuine Cat parts are guaranteed to function and fit commercial engines while maintaining a high level of quality and affordability.

Additionally, Cat Inframe Kit offers what no other brand can match, complete support through Caterpillar Authorized Service Centers. 

IPD is the key to winning the features section game. The IPD engine kit for ISX15 engines features upgraded and high-tech IPD-Steel pistons (closed bushings/skirt design), and compatible with APR (anti-polish rings) cylinder liners. 


IPD’s newest product, engineering, and quality assurance teams developed the market’s most advanced in-frame kit for the DD15 last year.

As IPD provides the latest coverage in on-highway applications through the launch of the updated engine kits for the DD15, the company is attesting to its commitment.

Due to its expansion, it now offers parts for Waukesha, Cummins, and Detroit Diesel for on-highways.

In addition to the marine and power generation markets, the kit is also available for the industrial, mining, construction, gas, and energy industries.

This Cat kit is compatible with the serial number 6NZ. The piston ratio is 18:1 as well. The piston, rings, & bearings are coated in ceramic.

The OEM cat liners are constructed from ceramic. Among the advantages are: in the event that you overhaul your Cat machine’s engine with an In-Frame Precious Metals Overhaul Kit – offered by Boyd CAT –  you can increase its performance & keep it in working order longer.

If you extend your machines’ useful lives, they won’t need to be replaced as often. You can save your company significant amounts of money.

The Cat Inframe Kit won the performance game. There is only one specific part number for easy ordering. Furthermore, they are designed for effortless handling, which streamlines and simplifies rebuilding, thereby minimizing equipment downtime. 


IPD selects the right gasket materials according to each application, not like most other aftermarket repackagers/suppliers that use cheaper materials in many applications just to cut costs.

IPD understands the extreme conditions drivers in diesel and gas-powered engines face. Aftermarket competitors often compromise gasket quality by choosing lighter-weight materials that are not suitable for heavy-duty or industrial applications.

Reduced sealing capability can result from lighter gauge materials, which can have serious consequences for engine lifespan and performance.

The Cat precise metals in-frame overhaul kit delivers a reliable and durable rebuild based on Caterpillar’s recommended practices for overhaul.

This kit includes the parts needed to perform a variety of repairs, ranging from essential maintenance to a complete overhaul of the frame.

Cat inframe kits are available for purchase over-the-counter from any of NMC Cat Machinery’s parts locations.

In this case, the Cat Inframe Kit wins. As well as delivering a high-quality and reliable rebuild, a self-contained kit is more affordable.

There is the option of pre-packaged, genuine Caterpillar parts, simplified ordering and delivery, and reduced selection errors.


IPD’s steel pistons are manufactured and engineered in the United States. Ultrasonic testing ensures proper ring insert bonding on IPD Aluminum pistons, which is crucial for pistons with high ring locations.

Cylinder liners are made from induction hardened materials to extend engine life. At IPD headquarters in the USA, IPD gaskets are made of premium materials of the highest quality. Providing world-class engine bearings, gaskets, pistons & engine kits.

Cat’s brand-new line of kits includes four levels: silver, gold, bronze, and platinum. Additionally, each kit comes with Cat fuel and oil filters, as well as exhaust manifold studs and thermostats.

There are also hold-down bolts & O-rings for the fuel injectors, along with the necessary gaskets and seals at upper and lower levels.

It’s obvious that IPD wins here. It continued to expand and grow worldwide for the next two decades, becoming one of the world’s largest parts manufacturers of diesel engines.
